Also stolen was a laptop and external hard drive, a record of her professional and personal life for the past nine years.
"There's photos of my children's births ... stuff that is totally worthless to the criminal but invaluable to myself, my organisation and my children."
At 9am the same day, a stranger rang to say they had found some of her items dumped on a sea wall on Beach Rd, with some items floating in the outgoing tide.
She later learned her car had been abandoned in a ditch near Dargaville and had been towed to Whangarei, at a $400 expense to her.
The car was badly damaged and not worth repairing. She said Pete's Towing was understanding and had waived the towage fee. They would take the car to the wreckers and keep what little money they got as payment.
"I wasn't insured," Ms Cleaver said. "Insurance was a luxury I couldn't afford. I've had to re-mortgage my house to find the money to start searching for a car. I've spent years paying the mortgage trying to get ahead - now I'm back at square one.
"The car is a vital lifeline to get the kids to school and to the doctors, and me to work. Over the last few days, I've relied on family and friends and it's been difficult."
Her message to the thieves was succinct: "They are cowardly, selfish, lazy thieves. There's no excuse to put other people in this situation for your own selfish gain. These thieves have no regard for the stress and strain this has put on an innocent family."
And she added: "Someone will be aware of a new LeapPad and fishing rod they didn't have before. Accepting stolen goods makes you just as guilty as the criminal."
Ms Cleaver has been heavily involved with community events and organisations since moving to Northland 10 years ago. For the past two years, she has been the business director for The Paper Mill - an organisation providing work experience and training for people with intellectual disabilities. She has also been the event co-ordinator for Artbeat for four years and was instrumental in establishing Channel North.
Her car was one of at least four police pursuits involving stolen cars over the Easter weekend.
Whangarei police spokeswoman Sarah Kennett said police spotted Ms Cleaver's car being driven south on Kirikopuni Valley Rd before it turned on to Houto Rd, near Dargaville. Police then chased the vehicle along the narrow metal road for about 2km before they found it abandoned in a ditch with the doors open and engine running. A police dog and handler were called but were unable to find anyone.
